As Danni Quee and the others leave for Helska, Carr kills one of those left behind he had discovered the severed communications cable.  Once Quee and the others reach the planet, they are attacked by a swarm of insectoids that they assumed were meteors.  They receive strange readings from the large mound that is buried in the planets surface.  A blob of material attaches to their ship and the head of the Yuuzhan Vong leader on the planet taunts them.  Other ships fire multiple blobs that force the ship down.  They are captured.  Quee watches as her companions are killed.  She is also tortured and tossed into a water pool.

Luke, Mara, Han, Leia and their children meet up with Lando on his new mining operation, Lando’s Folly.  The children compete at running the asteroid belt. Jaina sets a new course record, all while making it through a seemingly impenetrable wall of debris.  Jedi Kyp Durron greets the Solo children and invites them to join his squadron, known as the Dozen and Two.  They decline, although Anakin is keen on the idea.  Lando entices Han to head to Sernpidal to help him drop off some shipments.  He takes Chewbacca and Anakin with him.

Nom Anor leaves his planet behind, but not before taking leaving an explosion behind on the orbiting Mediator.  He speaks with the Yuuzhan Vong leader on Helska and they decide to attack Sernpidal as their next target.

Kyp picks up a signal from Danni’s ship and go off to investigate.  As they arrive, they are attacked by the insectoids.  Some of the fighters are shooting volcano type blasters.  The entire squadron is killed except Kyp who jumps into hyperspace.  The ship is severely damaged by several insectoids that made the jump onboard his ship.  He is not able to do much, but he hopes to make it to Sernpidal.

Danni Quee is joined by Miko from Kyp’s squadron.  She tells him that the Yuuzhan Vong are there to conquer the galaxy.  He is tortured by them in order to learn the mental limits of the Jedi.  They use something called the yammosk which is the brain of the Praetorite Vong (as the group on the planet is known).

Han, Anakin, and Chewbacca land on Sernpidal.  They meet the mayor of the city who tells them that one of the planet’s moons has been moving closer to the surface.  They learn that something on the planet is pulling to down.  While Han helps people escape, Anakin and the mayor search for the source of the issue.

Luke and Mara land on Belkadan to find it is basically dead from the infestation.  They enter the station, and Mara is growing weaker along the way.  They split up and R2-D2 begins downloading information.  He is interrupted by Yomin Karr who begins to fight with Mara.  His armor sheds off blaster fire and his organic weapons are effective against her lightsaber.  She attempts to use the Force, but she Yomin is not recognized.  Eventually, she is able to kill him, but is severely weakened.  Yomin tells her she is worthy as he dies.  They grab as many items from Yomin Karr’s stash and get off the planet.  They wonder if this warrior, the planet, and her illness are all related.  R2 replays the information he recovered about Helska and they decide to head that way.

On Sernpidal, Anakin finds the source of the problem is another organic creation that looks like a pulsating heart.  Han arrives with the Falcon full of refugees.  The mayor, refusing to accept that this will kill the planet, takes a thermal detonator and jumps into the heart destroying it.  Han tries to organize an escape for the people, but Chewbacca and Anakin hear a child trapped in some rubble.  As they help the child, Anakin is knocked out by debris.  Han struggles to keep the Falcon low enough for Chewbacca to climb in, but the turmoil on the planet is too much.  Chewbacca throws Anakin’s body to Han who is on the platform, but cannot get aboard himself.  Anakin wakes up and realizes that the planet is seconds from disaster and flies away.  Chewbacca is left on the surface, roaring defiantly at the moon as it strikes the planet.

Han is devastated at the loss and blames Anakin for leaving him behind.  As Han turns to go back for Chewie, he receives a distress call from other ships in the convoy that are now being attacked and destroyed by insects.  He also receives a signal from Kyp Durron so he changes course to rescue him.  He tells Han about the attack on Helska.  Several more attack ships appear and the Falcon jumps to hyperspace.

They return to Dubrillion and Han scolds Lando for Chewbacca’s death.  Lando reminds him that they saved 20,000 people in the process.  Leia looks for additional military support to hold off the impending attack and contacts the Star Destroyer Rejuvenator.  Han and Leia will copilot the Falcon.  Their children all vow to help as well.
